Abstract
In this study, we developed a fabrication method of conductive and transparent Ag mesh electrodes on flexible polymer film at temperatures lower than 100 °C. Random patterned Ag mesh film was fabricated on a flexible PET substrate over 15 × 15 cm2 by a self-assembly process. It became conductive by a coupling process at low temperatures. The coupled Ag mesh film showed more than 88% transmittance in visible wavelength and less than 8.2 Ω sq−1 in sheet resistance with figure of merit (FoM) value of 350. This transparent flexible EMI shield film fabricated with a coupled Ag mesh pattern showed high EM shielding effectiveness of −23 dB at 1.5–10 GHz frequency with a high transparency of 88%.
